Bowl of Chalk is cockney rhyming slang for Walk
This expression is also said as “ball of chalk“. We think the correct version is ball of chalk because the same slang is used in the military (“It’s gone for a ball of chalk”, meaning something is beyond repair.
Perhaps because of the cockney accent, over time ball of chalk came to sound the same as bowl of chalk.
